Requirements Process Patterns Via Events/Use Cases Suzanne Robertson The Atlantic Systems Guild Ltd 11 St MaryUs Terrace London W2 1SU Phone: 0171 262 3395 email:100065.2304@compuserve.com Abstract This paper illustrates how event/use case modelling is used to identify, define and access requirements process patterns. Event/use case partitioning is widely used as a way of breaking a system into manageable, business-related chunks. Each event/use case is then the subject of detailed analysis, design and implem entation. This paper illustrates how event/use case modelling can also be used as the basis for identifying and defining requirements process patterns. A proc ess pattern is also used to identify the appropriate requirements data pattern. Given a book of requirements process patterns, each project uses context analysis and event/use case partitioning as a way of accessing relevant patterns. Note: the terms event (reference McMenamin and Palmer T84) and Ruse caseS (Jacobson T92) to mean the same thing. I acknowledge that there are some differences in application and notation, but for the purpose of identifying and using proc ess patterns the models are interchangeable. Keywords: requirements process pattern, event, use case, requirements analysis. Copyright ) 1996 The Atlantic Systems Guild Ltd. All rights reserved.
